I have a 80amp breaker box. I'm wanting to but 4 breakers in it. A 30--20-- and to 15  breakers.  What size wire do I use from the meter pan to the breaker box.  They are both on a pole

You are leaving an awful amount of critical information out of this question.  Is this installation for a motor home or mobile home?
 
Meter pans are usually owned by the POCO, have you contacted them as to where they want the meter and pan?
 
Have you completed a load study to make sure that:
1) 80 Amps is sufficient and (2) You have sized and planned the branch-circuits correctly?
 
Are all of the circuits going to be 100% loaded, and all of them on at the same time carrying the full load?
 
If this is for a residence, than 80 Amps is not a sufficient load.  100 Amps is the minimum.

I assume this is a temp construction pole. We could surmise about everything but until we hear back??
