Try to get the rest of the players to turn against him with an "its Us vs Them" mentality.

This is your best bet. Failing that, there's not much to do if you can't out-produce him.

If you can get just one other player to help you, you can "double up" on a minefield (each player lays 100 mines in the same sector). Then when is uber-fleet runs into it (there's always an uber fleet!), counterattack. That trick will work once. And is a questionable tactic in some groups, so you might want to clear it with the game owner if you aren't sure.
