No... you really do not want to "make a hole" for the vocals in a mix and it is not necessary or desirable to take the mids out of the mix to make room for the vocals.
This is something you need to work on to get it right but here's what I do.
I put the mix together and have everything sounding good ..... nothing weak or scooped (beyond what sounds good) and then I drop the vocal in the mix. Pretty much centered and with a level that is appropriate for the genre of music. Country vocals are louder than rock vocals relative to the music.
Use compression, and reverb to smooth the transition of the vocal into the music mix. It shouldn't be buried in the mix nor should it stick out above the mix. Finding that perfect fit and level will take time and become easier with experience.
Don't make the mistake of trying to use too much reverb or other FX to make a vocal track fit. Listen to music that you like in the genre you are working and listen....really listen to how the mix was built, and where in the mix the vocals are setting. Then try to achieve that in your mix.
Practice makes perfect. Nothing beats digging in and having a go at it. And..... if you post your mixes in the songs forum, you can get the feedback of others here with advice on what is good and what could be done better. The songs forum is a great tool to use to improve your skills.
