I would use the same from what I remember the power setting on the approach was about 12-1300 lbs tq from the max of 3200 lbs tq, this roughly calculates to 39% power.
The go-around power setting is obviously 100% so a cruise power setting chart of 65-70% power would work.
You could always play it safe and use cruise tables for the approach and the climb charts for the go-around part after the missed approach point
