There are a couple things to keep in mind in terms of actually tracking.
Hip hop guys almost always want to double (sometimes triple) track vocals so Vocalign is your best friend here!
Organize your session beforehand. My standard hip hop tracks are usually:
2 main tracks for each verse and 2 (2 because most rappers will record a phrase and then go back and record the next phrase slightly overlapping or too close to make punching in very fun)
1 or two 'double tracks' for backup
1 or 2 ad lib tracks
1 whisper track
I will then do the same thing for the chorus and send each group of tracks to a seperate bus (verses and chorus)
Hip hop doesnt usually have much reverb (if at all) but I will use a bit on the chorus at times. I also like to pan my backing tracks pretty hard on the chorus as well as add a stereo image enhancer to really add some impact when the hook rolls around. A little delay on the hooks, slight mid scoops on the backing and you are really close.
Hip hop is really really easy compard to tracking most other things and if you take the time to set up your session well ahead of time you can crank through tracks like crazy as most dont change all that much.
Good luck.
