Smith, 23, started one game in the Six Nations as Rob Evans established himself at loose-head.
But, with Evans and Gethin Jenkins injured, Ospreys' Smith is keen to take his chance.
"Going from starting the first game in Italy to being on the bench for the rest of the Six Nations was disappointing," said Smith.
"But, looking back on it, it wasn't the worst thing in the world to happen to me.
"I was disappointed at the time, but it was my first full Six Nations campaign and I was still involved in every game, and it has made me more hungry."
