Unfortunately that's very common in Yorkies.
Was the lepto part of a combo shot or did the vet give it separately?
This happened to Ellie (she threw up, collapsed and went into shock...unresponsive pretty much). After a steroid and Benadryl injection, she was just very tired. The next day she was normal/almost normal.
Dogs can be elthargic and not have an appetite from this vaccine anyway for a couple days, so you probably have nothing to worry about. On the other hand, if there is vomiting, diarrhea or if his gums are anything but a nice pink, he probably needs to see the vet again.
How are his gums looking?
