Actually, I read up on this a lot as I have a Bruneian passport with the same issue. Your name should be written "Michael Tan Ying Qin" in last name, and if possible, you should indicate your passport has no first name. The first identifier in an MRZ is last name. Brunei and Malaysia don't differentiate because of the different cultures (even though Singapore is able to, go figure).
