I would just be very gentle and soothing. Let him have his space and reward with treats when he does positive behaviors. I would also avoid collars all together. Like one of the other posters suggested, get a microchip, and for walks only use a halter such as the buddy belt or something that stays away from his trachea. That would be my main fear, is the trachea as yorkes are prone for collapsed trachea. You might want to have him checked by a vet just to make sure all is ok with your babies neck and trachea if he continues to not be himself. I have a friend that warned me of the issue after her pup died from someone putting a collar on him, and the trachea collapsing.
