Good golly, he is spending the night, not moving in. LOL!
For a two day trip in a toy canoe(sorry Red, thought it sounded funny)you don't need a ton of stuff.
For food, I just pack sandwich meat and bread, some chips, and granola bars. I have a two gallon water jug I drink out of. I also have a small two man tent that will practically fold up into your back pocket that I toss in.
Used to, a good thick sleeping bag would do me. But as my bones get older, I have been packing a blowup mattress. These fold down to nothing too. And are they worth the money!
Just remember, the lighter you pack, since it is just one night, the better off you will be. Most of your time will be spent in the yak. This is not a camping trip. You don't need a lot of camping gear. And as JD said, pack some paper. Not for reading, for wiping! You can read at home. Enjoy a small fire with a good beverage and good thoughts about the day and the day ahead.
