The Foxes chairman died one year ago today along with four others when his helicopter crashed outside the King Power Stadium.
Puel was the manager on the night City drew 1-1 with West Ham, hours before the club's greatest tragedy unfolded, on Saturday October 27, 2018.
"October 27th is a special day for Leicester and myself. A day which is a mix of sadness and admiration," he said in a prepared tribute.
"A year ago, the death of President Vichai left us orphaned. He won the hearts of a club, a city and thousands of supporters, who formed a single family with him.
"He gave LCFC incredible strength while respecting the values of the club. He showed the players and fans that nothing is impossible... A year on, I still think of all he has built, all the good he created around him but also of the pride he has given to Leicester."
