You are doing everything correctly. There is a very good chance that she is picking up on your anxiety and frustration, and that may cause her to be anxious about going into the crate -- causing her to pee.
Or she is nervous/shy/too focused on you when you have her on the pad, expecting her to pee. Some Yorkies are successfully trained to go on command, but my guys won't do it. I try to make them use their pad before we go for a car ride (when I know we can't get out right away for a break). They are too preoccupied with me to use the pad when I hover.
Instead of making pad time all about the pad, try playing with her near the pad. The excitement of playing will often make a pup need to pee. If she goes to the pad and does it right, give the praise and reward like she just performed the best trick ever.
Hang in there, and good luck!
