how do I attach opamp to module

Solder it to an 8 pin SOIC to DIP adapter.

Use flux. Tack down opposite corners. Use a small tip or drag solder across the remaining leads (the flux will help prevent bridging).

What is a BrownDog 80302? Generally, ICs are specified, physically, in terms of their package and their pin-out. The AD825 is an 8pin DIP. What are you connecting it to?

The Brown Dogs are adaptors, soic to dip etc. Aamxyz, are you sure that's the right part #? I'm presuming you're trying to fit a surface mount opamp to a dip connection? Anyway, here are a couple of surface mount soldering tutorials to get you started, there's more out out there!
