Sure, try these:
"roll over" (obvious)
"show me some belly" (rolls onto her back and stays 'till I release her)
"say please" (sits when she's wants food, treats, etc. - usually does this without a reminder 'cause she won't get the treat 'til she sits anyway)
"right here" (runs to my pointing hand, touches it with her nose, then promptly sits where I'm pointing)
"go outside" (pees on command - had to do this, and the next one, 'cause housebreaking her was soooo hard)
"go potty" (poos on command - obviously, I can only give this command once a day; if I ask her to potty when she doesn't need to, she'll squat, hold for a minute, then look over at me with the funniest "ok, Mom?" look on her face)
"sit pretty" (sits on her haunches with her paws curled up against her chest - we're still working on this one, but ohhhh, it's so cute!)
I'm sure others have tricks they can post, too. Our Yorkies are so intelligent and happy to learn!
