Turan, 27, moved to Spain from his homeland Turkey in 2011, having appeared 127 times in the Super Lig for powerhouses Gala.
His departure to La Liga earned Galatasaray €12 million, and Turan said the 0-0 draw in Izmir was an emotional contest.
"It has been a very happy day for me day because Galatasaray is my home. It was a very special match despite being a friendly because there was a spectacular atmosphere," Turan said.
The friendly was organised as a fundraiser for the families of the 301 people who died in the Soma mine disaster in May.
Turan, a Turkey international with 72 caps, said the meaning was not lost on the fans.
"I was very moved, but when the match started I focused on the game, which was what I most cared for," he said.
