Playing in his rookie campaign in 1993–94 Smolinski tallied 31 goals and 51 points. After a 31-point season in the shortened 1994–95 campaign, Smolinski was traded in the summer of 1995 alongside Glen Murray to the Pittsburgh Penguins for Kevin Stevens and Shawn McEachern. Playing in his only season with the Penguins in 1995–96, he scored a career-high 40 assists and 64 points. However, Smolinski and the Penguins could not agree on a new contract in the off-season and he subsequently sat out the start of the next season, playing for the Detroit Vipers of the IHL. In November 1996, general manager Mike Milbury of the New York Islanders traded defenceman Darius Kasparaitis and rookie Andreas Johansson for the rights to negotiate a contract with Smolinski.
Smolinski played three seasons for the Islanders before being traded in June 1999 as part of an eight-player deal that saw him, Žigmund Pálffy, goaltender Marcel Cousineau, and 4th round selection previously acquired from the New Jersey Devils (Daniel Johansson) traded to the Los Angeles Kings for Olli Jokinen, Josh Green, Mathieu Biron, and a first-round selection (Taylor Pyatt). Smolinski played four seasons for the Kings, before being traded to the Ottawa Senators at the trade deadline for defence prospect Tim Gleason on March 11, 2003.
During the 2004–05 NHL lockout, Smolinski was an assistant hockey coach at Cranbrook Kingswood before briefly playing for the Motor City Mechanics of the United Hockey League (UHL). Returning to the Senators for the 2005–06 season, he was traded in the subsequent off-season on July 9, 2006, to the Chicago Blackhawks in a three-way deal with the Senators and San Jose Sharks. Smolinski started the 2006–07 season with the Blackhawks but was later traded prior to the trade deadline to the Vancouver Canucks on February 26, 2007, for a conditional second round draft pick. Becoming a free agent in the 2007 off-season, Smolinski signed a one year contract with the Montreal Canadiens on July 2, 2007. On October 22, Smolinski played in his 1,000th career game in a game against the Bruins.
After his stint with the Montreal Candadiens, Bryan Smolinski began an assistant coaching job for a Michigan high school team, Birmingham Unified. With Smolinski's help, the team became District Champions for the first time in four years. Without an NHL job, on February 24, 2009, Smolinski signed a deal with the Port Huron Icehawks of the IHL. On April 30, 2009, Smolinski signed a deal with the Milwaukee Admirals of the AHL. Smolinski then signed with the Flint Generals for the 2009-10 season where he netted 24 goals and 25 assists in 48 games with the now defunct IHL club.
