Decrease number of sets, but maintain intensity and frequency. This works really well for me.
If I know I'm just doing 1-2 sets per exercise, I can get a workout in in 30mins. Even one "good" set every five days maintains strength and muscle nicely. The key is to not let your reps and weight slip much. Keep the demand there with one strong set every five days and your body will maintain the muscle mass.
Then you can let the diet strip the fat off, and get back to pushing for lifting progress later on when you've leaned out.
