It's pretty simple, actually. Embarrassingly simple, in fact.
Throw up a zone conjuration. Wall of Fire or Blade Barrier works best, though Cloud of Daggers will certainly work in a pinch.
Now just have your party use forced movement on your foes through the conjurations. You'd be able to do a lot more damage than you would normally.
For example, say your wizard threw up Freezing Cloud. Your ranger then uses, say, Thundertusk Boar strike and pushes them through 4 squares of Freezing cloud, That can add up to quite a bit more damage if your friends use their pushing powers, too.
