Sri Lankaended their first innings all out for 257 early on Friday, but the early dismissals of Travis Head (21) and Marnus Labuschagne (four) gave the hosts hope of limiting the tourists' total.
Smith, who surpassed 10,000 Test runs in the first match of the series, survived an lbw review from the first ball he faced and eventually ended the day on 120 not out.
It was his 36th red-ball ton, with only Sachin Tendulkar (51), Jacques Kallis (45), Ricky Ponting (41) and Kumar Sangakkara (38) scoring more centuries in the format.
Carey, meanwhile, smashed an unbeaten 139, with the duo set to resume on day three with Australia boasting a 73-run lead with seven wickets in hand.
Speaking at stumps, Carey lavished praise upon his batting partner and highlighted the stand-in skipper's frequent use of the reverse sweep, which kept Sri Lanka on their toes.
"To be able to focus for 250 balls in these conditions... it's another 100 on his CV, and he's going to go down as an all-time great," Carey said of Smith.
"It certainly surprised me when he went for a reverse sweep without a helmet on. He's got some nice teeth, which aren't cheap!
"That's the quality of the player, he's able to solve problems on the go."
Looking ahead to the resumption of play on Saturday, Carey said: "We are in a commanding position.
"We want to score as many as possible in the first innings, as batting can get tricky later."
Kusal Mendis, who ended Sri Lanka's first innings unbeaten on 85, said: "Australia were superb. They bowled well and they took on our spinners well.
"We need to keep their first-innings total to as little as possible. The bowlers will be fresh tomorrow and they will be raring to go. We want to get back into the game."
Mendis' knock was the second-highest unbeaten score in Test history by a Sri Lanka player batting at number seven or lower versus Australia, after Romesh Kaluwitharana's unbeaten 132 in 1992.
