Unless you deleted them, which I doubt, you should still have the torrent files. In that case, you just open them with utorrent and they will restart/pick up where you left off.

If you truly have lost the torrent files, then go back to the torrent sites where you got them and re-download a new torrent file. Make sure that you point utorrent to the folder the downloads go into, and it will do the rest, and pick up where the downloads left off. You should have bookmarked the torrents so you can find them again at the sites.
