Without being there to see and hear the barking, I can't say if she is saying come play with me, I am afraid, I want to fight or something else. I wish I knew why she was barking then we could work on the cause.
You can correct the barking by a firm NO and squirt her with water, turn around and go the other way. You may have to turn around a lot at first. You have to break the trance zone they get into. After you walk the other way a few yards and only in extreme cases, you may need to squat down and gently cup her mussel and say No firmly. Do NOT Squeeze the Muzzle or shake, always remember correct not punish. One advantage is you can pick up a Yorkie make eye contact and say NO when cupping the muzzle. The correct way to cup a muzzle, is like you are holding a rail, thumb and first finger facing you and pointing down. Your little finger is facing the doggie. NOT like holding a hose, you can accidently apply too much pressure.
Teach her the Quiet command at home and treat when she is quiet. Once she has learned Quiet you can use this on walks also and may not even need a water spray bottle. If you do not know how to teach the quiet command I can help you with that.
