Have you emptied your Recycle Bin since you deleted the Tray? If you haven't, then open the Bin, find the file or folder, and restore it. If you deleted a bunch of stuff at one time along with the Tray folder, you'll have to do that again.
The game will create another Tray folder. When it does, it gives you all the Maxis lots and sims that populate the tray when you start the game the 1st time or start a new user folder. Then you can open your save and save all of your custom/modified lots and sims to your tray so you can get most of what you lost back if you can't recover the folder from your recycle bin.
Hope this helps.
