Some wizard powers I've cooked up (a bit emulating the stuff that Gandalf and Saruman fling around in the first LotR film):
Unseen Force Wizard Attack 1
You project an invisible force, hitting your enemies like a sledgehammer.
At-Will * Arcane, Force, Implement
Standard Action Ranged 10
Target: One creature
Attack: Int vs. Reflex
Hit: 1d6 + Int damage and push 2 squares.
Increase damage to 2d6 + Int damage and push 1 + Int mod. squares at 21th level.
Binding Force Wizard Attack 1
An invisible force flings your enemy away and pins him down.
Daily * Arcane, Force, Implement
Standard Action Ranged 10

Sustain Move: Only if the attack was successful. The target is immobilized until the start of your next turn.

Telekinetic Force Wizard Attack 7
You direct an invisible force, pushing your enemy around.
Encounter * Arcane, Force, Implement
Standard Action Ranged 10

Seismic Impact Wizard Attack 15
An unseen glob of force ripples through the air, impacting with considerable force.
Daily * Arcane, Force, Implement
Standard Action Burst 2 within 10 squares
Target: Each creature in the burst
Attack: Int vs. Fortitude
Hit: 6d6 + Int force damage and push 3 squares from the centre of the burst.
Miss: Half damage and push 1 squares from the centre of the burst.
Of course, feedback could help - I'm not really sure about the sustain of binding force - part of me says it would be better as a standard action, but with a bit of damage added.
Cheers, LT.
