Okay So I am mixing my Vocals in with my guitar track. Guitar was mono and vocals were mono to begin with. Spots where the vocal comes in the guitar is kind of covered up with my vocals volume. So after it's all done. Would I just simply MIX Exact guitar Track with that track, and what do I do? completely pan left ?

What I would do is put the guitar through a stereo delay, like the Sonitus, and delay one channel by about 17 ms. This will put a guitar in the left channel and a delayed version of the guitar in the right channel. So it will sound like the guitars are on the "edges" of the stereo field, with the vocal plopped down in the center. Try it and see what you think.

Sounds cool, I guess I could also just add 17MS to the extact track without the vocals and lay it in the background ? Be kind of an echo :)

No, you need the stereo width to create a "hole" in the soundstage for the vocal

Like Anderton said, the stereo delay is a good way to take your guitar out of the stereo center and leave space for your vocal.
Another way would be to double your guitar track, panning one left, the other right. But don´t just copy/paste your track to double it. This would just result in a louder guitar in your mix. ;-)
Instead, record your guitar track two times and then pan each track to the left and the right. Difference is: even if you play the exact same as in the first take, you can´t avoid (even little) changes in your timing and tuning. This creates a stereo-widening effect, leaving space in the center for your vocals.
 
If you still need more space in your stereo center, try a MS compressor on your guitars group. It compresses only the center of your guitar mix, leaving the left and right panned signals untouched.
By the way: does anyone know, if Sonar has a MS compressor? Still haven´t found one ;-)
I´m using Destiny mkII for MS compression. It´s easy to use and freeware ;-)

This is my approach. Maybe you give it a try ;-)
