SOURCE: broken timing belt
Since it is an interference engine, the chances are very high that the valves were damaged, especially if someone tried to restart it after it stopped. As unlikely as it may seem, there is still a chance that it survived. I would try putting the belt on and see what happens. There is a way to check without putting the belt on, but it probably involves tools that most people don't have access to. If you decide to try the belt, make sure that you don't cause further damage when you're moving the crank and cam to the correct position. I like to pull #1 spark plug and put a wooden dowel in the hole and turn the crank so that the piston is positioned half way down it's bore. When you do this, you want to make sure you turn the crank in the direction that insures none of the pistons will cross over top dead center. When all the pistons are half way in their bores, you can now turn the cam into position without worrying about any of the valves striking the pistons. Once the cam is in position, now turn the crank in the direction that brings it up first and into position. Attach the belt, and give it a try. If it runs, let it warm up before you breath a sigh of relief. When the engine is cold, it is running rich and fast, this will disguise a slightly leaky valve. When the engine is warm and the idle has dropped down, if it is smooth, you are home free, if it is rough or won't run, it's time to pull the head.

A year is not a good sign. The belt should not have come off in that span of time. I would make sure you do not have a worn out idler or tensioner pulley bearing before installing your new belt or reinstalling the original if it is not worn or damaged.
You will find one or two small pulleys involved with drive belt. One of the smaller pulleys will be an "idler" pulley and simply redirects the belt to a different accessory. The other small pulley is considered a "tensioner" pulley, it is spring loaded and keeps the correct tension on the accessory belt.
The tensioner pulley will have a "squared" hole in the bracket or a bolt through the center of the pulley. In either case you will use a wrench to pry the tensioner pulley arm in the direction that loosens the belt. Once tension is relieved, pull the belt off a pulley and remove the belt. You will reverse the process to install the new belt.
Good luck and let me know.

For the 2000 Chevrolet Tracker:
Most modern vehicles have the Belt Routing Diagrams on the undeside of the Hood. But the sometimes disappear.
I do not know if you have the 1.6L In-Line 4-Cylinder, or the 2.0L DOHC In-Line 4-Cylinder. Nor what Engine Options you have (AC/No AC, etc.).
Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com!
