what you're describing is how most of us work anyway. but we need to know a little more about your setup. if you have a multi channel interface, you can either use a channel output (eg output 3 while output 1-2 are for everything else - band whatever) to a channel on your mixing desk. send to your aux on which you have the reverb which is returned to the desk. this way your are mixing partially outboard for FX. the other way (esp if you don't have a mixing desk) is to have your outputs of your interface go directly into the reverb unit and mix the signal there. be careful not to "resend" the wet signal back to the reverb unit otherwise you will have a feedback loop. so you might have the voice mixed in with everything else coming out of channel 1-2, monitored through inputs 1-2 that have been set to play out of channel 3-4. that way you are listening to everything - dry recording and band to FX back into logic and monitored.
