Here is a quick check list of info you will need, build a table or spead sheet and ask for information at the top of each column, each employee detail can be entered in rows below. Unless you are sure you have the contract you will only need basic info such as pay rate, hours of work etc.
I'm sure I've probably missed out a few things from the list, but hope it helps!
