I usually get the drums in my head so I would be better off doing a rough recording of the guitar parts then get the drums down and the bass and then re-record the guitar.

It sounds like you're composing while recording those compositional ideas.  The tempo problems are going to be inherent with that method though. Learn to edit well. I've written and recorded a lot of songs with that method - and it works really well for catching fresh ideas and even better accidents. After going through all the pains of fleshing the song out and getting the rhythm sections tightened up, plan to go back and try a clean take on your guitar part. What you're doing is the best way for a one man band to write and record in my opinion.

It does seem like the accepted method is to record the keeper guitar parts after the drums and bass, but there have been many times where the original scratch guitar part, or even the warm up takes, have ended up being the most suitable takes for the finished song.
So, save all takes and never delete anything until the project is finished.
It really comes down to, every song is different and you never know what's going to work (sound best) until you hear it in context with the other tracks.

Ive been working on a new track by myself so I've got all my rhythm guitar wrote that's recorded as my guide for the rest of the instruments I'm just building my own drum pattern up which is quite time consuming but its worth the hard work.
 
My next plan is to build all the drums up get the bass down and then re-record the guitars and then get my vocalist to get his bits done providing he's happy with my work.

I usually do a dummy track with an acoustic then build around it. If the song has a melody or vocals I record that with a guitar. I try to do the whole song on one track first. Then build from there. Everyone I've talked to has their own way that works for them. There really isn't a right or wrong way I suppose. For me each and every song I do is different. It's amazing to me has fast time goes by when I'm doing it!

I have a slam dunk approach I use on every song.
 
1. I play around on the guitar to get a feel for what I want to play organically and tempo wise.
 
2. I have a pre-built blank Sonar song that has my various tracks and busses set up the way I like.  The first couple of tracks are TTS-1 VST tracks using channel 10 (the drum channel).  TTS-1 has a very clean drum sound.  I created a basic drum beat for that track - 8 hihats on each of the 8th notes, and an alternating kick drum snare drum on the quarter notes.  I only actually have that pattern set on one measure (it's a Midi block of these notes).  Then I can either turn it into a loop and drag it out for 100 to 200 measures, or I can just copy it and paste special it, so that it does 100 repeats etc.  I actually have this file set up with 150 blocks/measures already in place.  I like the blocks method because I can then use Clip colors to color in sections later, like chorus is green, verse is yellow etc.  Handy for the eyes in addition to markers (even when these clips are later muted because I've moved on to real drums).
 
3. So restating 2 above, I have one track which has 2 measures of count in (which I can mute separately as I choose), and then the second track has the 150 or so blocks.  Since this is all MIDI and plays through TTS-1, I can set the tempo to whatever speed and I have a great basic drum track to play guitar against.  Much more natural than trying to play against a click track.
 
4. I record a scratch guitar take, or set of tracks that make up the scratch take, that allow you to figure out how you want the song to basically be structured.
 
5. Once I have the structure, I can now start the process of adding real tracks, whether that's a bass track, some real clean sections of guitar parts with their various styles/effects etc., keys, real drums, vocals, and so on.
 
6. Obviously after real stuff is in, I mute or even delete the scratch guitar take(s). And as mentioned, I mute the TTS-1 drum tracks but leave them in for the color coding which is a nice visual of how the song is structured.  (That works great for my drummer by the way - he can look at the colors as he's playing against the song and know what changes are coming up in advance so he can hit the accents).
