Tushar Arothe, who stepped down from his position last week, mentioned "personal reasons" as the main reason for his resignation.
Power will supervise the camp in Bangalore from July 25 to August 3. A source to the Indian Express said, "Powar had been asked to oversee the camp since the team does not have a head coach. He will be involved in planning with assistant coach Biju George. The BCCI has already invited applications for this post, but the process will take time."
Powar took up this offer after quitting as the spin coach of the Mumbai Cricket Association earlier this year.
Having made his debut in 2004, Powar played 31 ODIs and 2 Tests in his career. He was a consistent performer in domestic cricket and played first-class cricket for 16 years.
In 2008, he made his IPL debut for the Kings XI Punjab and continued to play in the first three seasons for them. He played for Kochi Tuskers Kerala in the IPL in 2011 and again played for Kings XI Punjab in 2012.
In November 2015, he announced his retirement from all forms of cricket.
