If the first player chooses to resolve Tears of Lys first, and Drogo is not saved, he will not return to the hand because he is no longer in play (which is required for Waking the Dragon's delayed effect)
If the first player chooses to resolve Waking the Dragon first, the poison token is gone because the character left play. So, Tears of Lys won't take effect.
Edit - Change Dany to Drogo and add note about saves.
Both of these cards create delayed effects which resolve at the same time. When delayed effects resolve at the same time, the first player will choose the order.
