My best advice is to write it in plain and simple English. A ToS doesn't have to be written in legalese. For a good example (that got an award for being so good), check out BillMonk's ToS and Privacy Policy. They wrote it themselves with the help of a Nolo book (available at your local library) if I remember correctly. If you really want to use legalese, just find a ToS from a website similar to yours and adapt it to your specific needs.
