Think about getting your knees forward and out early and get them set about halfway down. Now, hold them there throughout the remainder of the descent, and keep them there until you're halfway back up, at which point they can move back over your heels.
When your knees are set in place, driving your hips up will actually result in them going straight up, not up and back as they're doing right now.
Holding the knees in place can be hard to do. I sometimes focus on tightening the muscles down the front of my shins before the rep even starts, and holding that tension throughout the rep. Other folks can chime in with cues they've found useful.
