Bale struck in the 1-1 draw.
Lloris said: "It's great to see Gareth in such good form straight away. Of course it is just a friendly match but it is good to have time on the pitch.
"Maybe he would have preferred to be with his family on his birthday - he couldn't have any cake because we were playing! But he showed what a good professional he is and I am sure he can celebrate with them tomorrow.
"We enjoyed the game. The object is to make sure we are ready for the start of the season and that is what we are all working for."
