The 24-year-old right-back topped 100 league games towards the end of the season.
And the Manchester City academy product has made 110 appearances in all since signing in 2012.
Smith also scored his first senior goal during Town’s 5-2 FA Cup third-round replay defeat at Reading in January.
“I’d like some more, and it’s not for the want of trying,” he said.
“The system David Wagner favours means I get upfield more than before, so I’ll keep plugging away.”
Smith, from Frodsham, near Runcorn, is enjoying life under the German head coach.
“The boss is always there for us and ready to tell us what’s needed and where we can improve,” he explained.
“We have been a bit inconsistent in terms of results since he came in.
“But you can see the impact he has made and I think we will keep progressing.
“Pre-season will be an important time for us.
“The week in Marbella straight after he was appointed (in November) was really good.
“We have two pre-season trips coming up (to Sweden and Austria), so they will help.
“It’s not just about working on fitness and tactics, it will help with team bonding too.”
Smith is under contract until 2018, with Town having the option of adding a further year.
“I’m more than happy here and it’s great to be a part of things,” he added.
