Just wondering what thoughts you have regarding balance? e.g. at the moment Sense is a major point of difference between mages and other classes. But if you implement Rods of Detection that mimic it then suddenly all classes will have the same ability, and no one will ever hit a trap again...
So, that said, some ideas:
Rod of Trap Detection: detects traps in a cone, blocked by walls. So you can use it to hunt for traps where traps may be (e.g. vaults), but not practical to use it everywhere.
Wand of the Eye: target somewhere (using normal targeting rules). Creates a light-source at that point (large radius), and lets you see everything visible from that point while the spell lasts. Used for seeing around corners
Wand of Lasso: Target one npc in range; bring that npc next to you (resistable).
Wand of Targeting: Increases your to-hit and critical chance against the single target.
Wand of Doors: Creates a portal on a wall that you can walk through. Basically, it works like probability travel, so the exit portal is on the other side of the wall. The portal is either permanent or lasts a certain duration. NPCs can use it too.
Wand of Patience: Creates a slow-moving projective (say, 80% normal walking speed) that explodes when it finally hits a target.
Wand of Luring: Target a square. There now seems to be something very tasty there! Essentially, it's like taunt, but it specifically works on dragons and canines.
Also I heartily endorse Final Master's idea of a Wand of Smoke
