Couple ideas...

Take away tools. For instance: feeder only does offense, you only do defense.

Work on slips, evasions, fades, ducks, bob/weave, shoulder roll etc by having someone feed you strikes with your hands behind your back. Do one or two minute rounds that way.

I do mostly "non-sport" stuff: start from a fence, have a feeder approach you. Back off by way of angling away from your feeder, respond with an interception or default cover. Feeder should vary his timing, speed, distance, and types of attack. S/he can do a single or compound attack, then reset.

My fave timing/distance drill is (using hand distance in this example): Feeder moves around, you maintaining the fighting measure. Feeder throws a half-speed, and obvious hook. If you're out of range, wait for it to pass, tap feeder on the shoulder with your lead hand (forcing you to insure correct distance, availability of attack). If you're within the range of his attack (though you're endeavoring to maintain fighting measure, as I mentioned...), step back out of range, then as the attack passes, step back in range and tap feeders' shoulder with the lead hand again. This drill can be modified, adding more ranged attacks that can be responded to with interceptions (finger jab, straight punch/interception of attacking hand AKA "cornering" simultaneously, teep/jab kick...). It's a timing/distance/generalship drill, but has a great added benefit of forcing you to move your feet.
