Moon eye hair jigs would be in my kit; so would original Rapalas, sizes 9, 11, maybe 13 even. Dark colors would be best but some brights as well. I would take a pack or two of salted minnows.
The biggest help you could give him would be a portable fish finder of some kind. Any kind. Anything is better than nothing in that regard. There are lots of portable ice fishing setups which would work well in a small boat like that with a kit to put a transducer out. He could buy one on Ebay and turn around and put it right back on there when back from his trip even.
