I’m using a Canon T2i with a Canon 430EX II off-camera on a YN-622C receiver, and a YN-622C-TX on the camera. The flash fires correctly, but changes made on the transmitter don’t affect flash output. I currently have everything on the same channel/group and the 430EX II set to Slave mode. How should the flash be configured so I can control E-TTL or manual power from the YN-622C-TX?

You need to set it to E-TTL or Manual mode, not to Slave mode. The YN622C-TX and YN-622C combine to create the equivalent of an off-shoe cord. The camera sees the transmitter as a compatible Canon E-TTL flash and the flash sees the receiver as a compatible EOS camera. So the flash is acting just as if it were mounted on the shoe, not as an optically controlled slave.

Take the 430EX II out of Canon optical Slave mode.
With the YN-622C system, the transmitter and receiver act like a radio off-camera E-TTL cord. The camera sees the YN-622C-TX as a compatible Canon flash controller, and the flash sees the YN-622C receiver as if it were the camera hot shoe. That means the 430EX II should be set up as if it were mounted directly on the camera, not as an optical wireless slave.
Set the flash to normal operation, then control it from the YN-622C-TX in either E-TTL or Manual mode. If the flash is left in optical Slave mode, it listens to Canon’s optical wireless sensor instead of the hot-shoe contacts, so power changes from the YN-622C-TX won’t take effect.
In short: same channel/group on the YN units, but the flash itself should not be in Canon Slave mode.
