Having previously coached
India A, Bangar began working with the
Kochi Tuskers as batting coach in 2010. In January 2014, Bangar was named assistant coach of
Kings XI Punjab ahead of
IPL 2014. He was promoted to the role of head coach during the season and coached them to final, the Franchise's best IPL performance to date, where they lost to
Kolkata Knight Riders. He went on to Coach Kings XI Punjab for three years until he had to give up his role to comply with the
BCCI's conflict of interest rules. In August 2014, he was named batting coach of
India after an embarrassing Test series defeat to England. He was named head coach of
India national cricket team for
Zimbabwe tour in June 2016. After
Anil Kumble was appointed as India's head coach for a one-year tenure starting with the tour of West Indies in July 2016, Bangar was reappointed as the team's batting coach. Many Indian batsmen, including Indian captain
Virat Kohli,
Rohit Sharma,
KL Rahul and
Ajinkya Rahane, have credited Bangar for contributing to their growth. After Anil Kumble's tenure as head coach ended in June 2017, where Indian Team lost in the Finals of the ICC Champions Trophy, Bangar carried out the role of Interim Coach to India's tour of West Indies in June–July 2017. After
Ravi Shastri's reappointment as head coach, Bangar was promoted to the role of Assistant Coach till 2019. Bangar's coaching has been credited for improving India's lower order. Bangar's tenure as batting coach saw India create several records, with Indian batsmen scoring over 150 centuries and India winning 30 tests out of 52 tests played, 82 ODIs out of 120 ODIs and the Test team staying at top of ICC Test Rankings for over three and half years during his tenure of over 5 years as coach. In 2018,
India toured South Africa in what was considered a mixed bag, with India losing the test series 1-2 but later winning the ODI series by a record 5–1 margin, a feat not accomplished by any other Indian team. India then lost a closely contested
Test Series in England by a margin of 1–4, with India's batting and Bangar's role came under criticism for unable to chase a 4th innings target of 193 set by England in the first test. However, later India won a
historic Test Series in Australia 2–1, thus ending the 2018 season with 4 rare overseas Test victories in South Africa, England, and Australia. Bangar's contract with BCCI ended in 2019 after the
2019 World Cup where India lost in the semi finals, although it was widely debated that why only one member of the coaching staff's contract was not renewed. As compared to previous foreign coaches, Bangar's performance was notable. Indian batsmen under him scored a total of 150 centuries including 89 overseas centuries, across formats. In February 2021, Bangar was appointed as a Consultant for
Royal Challengers Bangalore for the
2021 Indian Premier League where they finished third in the table and qualified for the play offs. On 9 November 2021, he was named the New Head Coach of
Royal Challengers Bangalore for the
2022 Indian Premier League, a season in which RCB gave their best performance since 2016 before losing the Qualifier 2 match to the eventual finalist
Rajasthan Royals. Ahead of
IPL 2023, Bangar was appointed Head of Cricket Development at Punjab Kings, with whom he had worked already (when they were Kings XI Punjab). == Personal life ==
