I would do a mini linear progression back to your previous weights but use sets of 5 for all of your warm-ups. Next time you lift, I would ramp sets of 5 until you find a weight you feel you should stop at and do 2 top sets at that weight. Use where you stop as a new reference point and aim to take 10-20% jumps each session every 48-72 hours until you return to previous weights. Be conservative that first day back.
