Basic Mixing

Hello, Ive just started mixing vocals a little while back and finally decided to branch out for some help.

Any Tips you have I'm willing to listen, But the question i have for you now is.

I have a lead vocal recorded in Mono and its ran threw A Reverb bus, A Delay bus and another stereo bus with no effects on it.

I was wondering how i should pan my buses or if you have a different idea for a setup that may give me a better sound.
