Not sure how detailed you are looking for but you can check out the following sites and see if there is anything you like.

You might also want to take the main world map and then just change up the dungeons a bit. You can get some basic dungeon maps at the following link;

There are lots there so have a good look and they print out really nice too.
Another option is to just redraw the official Icewind Dale maps on a piece of graph paper to make it more playable in a tabletop environment.
