Smith played his high school ball at Oldham County High School (Buckner, KY), where he was a standout forward on the high school team and record-setting wide receiver on the football team. He also played on the Kentucky (high school) All-Stars in their annual two-game series against the Indiana All-Stars. After two years of junior college basketball at Southeastern Illinois College, Smith was rated as one of the top JUCO prospects and committed to play ball for Rick Pitino at the University of Louisville. But he backed out of the commitment and entered the 2004 NBA Draft instead.
Smith led Haifa to its first Israeli League title ever during the 2012-13 season, his first with his team, along with teammate Gal Mekel. In the following season, 2013–14, Smith was awarded the Israeli Basketball League's Most Valuable Player Award, after leading Haifa to the finals for the second time in a row. Haifa, however, could not win the title again, after losing the finals to Euroleague superpower Maccabi Tel Aviv.
In August 2013, Smith was naturalized as a Venezuelan to participate with the country's national basketball team. In 2014 he was chosen as an MVP of the Israeli AllStar match.
In June 2014, after two successful seasons with Haifa, Smith signed a three-year contact with Israeli team Hapoel Jerusalem.
