spanking a dog with a newspaper (or anything) is very outdated practice along with rubbing their nose in it etc. I personally would never hit (tap) a Yorkie as they are so sensitive. Generally I find when the potty training isn't working either the dog is not understanding something, too young to expect him/her to be trained, or the owner is not getting the dog on a feeding schedule and getting him/her out enough OR the owner is giving dog run of the house too early and not watching the dog. It can feel like a long road to housetrain a Yorkie but the patience, consistency and positive praise will certainly pay off in the long run with a life time of joy. Hang in there and put that newspaper away or save it for reading only
