Hello and welcome to YT. Congrats on yotu new pup. I would start out with a x pen and a potty pad until he gets a little older. Enough for him to hold for a few hours. Then I would start crate training. There is an excellent resource book called "How to Housebreak Your Dog in 7 Days". Is very helpful. Yorkies are not as easy to housebreak.
Here is the schedule that they are using. It seemed to work for Galen. Good luck
