Both Smith and Warner were barred from participating in the lucrative league last year after their involvement in the scandal.
The duo, who are serving one-year international bans that end later this month, recently joined the Australian team in Dubai as part of their reintegration after the scandal in South Africa that rocked the cricketing world.
Both players, who are also returning from elbow injuries, would be eligible for part of the upcoming ODI series against Pakistan, but selectors decided it would be better to ease themselves back into form at the IPL.
Smith returned to his Jaipur-based franchise Rajasthan Royals, while Warner joined Sunrisers Hyderabad.
"Great to be back with the @rajasthanroyals here in Jaipur. Very excited for this years IPL," Smith wrote on Twitter.
Warner also took to social media to thank his franchise for its "loyal support" all through his international ban, which ends March 28.
"Great to be back here in Hyderabad with @SunRisers I can't thank the franchise and fans enough for your loyal support over the last 12months. Time to get back into it," he wrote.
Warner - who led Sunrisers to victory in the IPL's 2016 edition - and Smith were suspended just ahead of the 2018 edition by the league's governing council.
The "sandpapergate" scandal in Cape Town also saw opening batsman Cameron Bancroft banned for nine months. "It's been awesome. It's like we didn't really leave, the boys were very accepting of us coming in and with open arms," said Warner in audio comments supplied to AFP Sunday.
"A lot of big hugs and cuddles. It's been great.
"It's good to see the spirit they're in after a great series win in India and I am obviously looking forward to watching them play against Pakistan here and hopefully they win that series as well," he added.
The "sandpapergate" scandal in Cape Town, which also saw opening batsman Cameron Bancroft banned for nine months, had far-reaching consequences for Australian cricket.
