So the student doesn't want a textbook? That is interesting as usually students want to have a book, depending on their level. You can always try
http://iteslj.org/questions/ too for lots and lots of questions. I suggest having a topic and some vocabulary and they talk about it. Also make sure that the student doesn't want any book or homework. In my experience of 1-to-1 classes are fast paced with highly motivated students who want lots of homework and lots of work from the teacher too. It's enjoyable once you get used to each other.
Best of luck!
