Get your self a spear, ice saw, chisel, ice tongs, and a decoy. You can also buy large live bait if it is legal on the lake you're going to and use that as bait. Use a pin instead of a hook so it won't count towards your line limit if you are also using tip ups. Also bring a few dried egg shells with you. After you cut the hole crush them up and drop them down the hole. It gives you a much better visual reference on the bottom and will make the fish much easier to see.
