How should I teach university tutors?

I have been asked to help teach engineering and computer science tutors how to tutor. Suggestions, and contributions of syllabus, references, videos, exercises and the like would be most welcome. About half the tutors have some previous experience, half are new. Some are graduate students, some are from industry. We have until February next year to come up with a program, and then two days to teach them. There will be experienced tutor trainers as part of the team, but I am new to this (I have been a tutor and a teacher and trained to teach students, but not train the trainer).
