Here are some panning tips I found in some article:
-main vocal- middle
-background vocals- balanced throughout the panning spectrum
-percussions- snare & bass drum in the middle, everything else balanced throughout the panning spectrum
-bass- middle
-keyboards- left part of the keyboards completely left, right completely right
-multiple keyboards- every keyboard balanced on it's side
-guitar- close to the midle
-2 guitars- every guitar balanced on it's side
-brass, pipes- 1-opposite to the guitar
Ã, Ã, Ã, Ã, Ã, Ã, Ã, Ã, Ã, Ã, Ã, -more- balanced widely
