Following their 1-0 victory against Cardiff in the Premier League last week, Puel flew to Bangkok with some of his players to attend a mourning rite for Vichai, meaning preparations for Saturday's match against Burnley were disrupted.
The club also honoured Kaveporn Punpare, Nusara Suknamai, pilot Eric Swaffer and his partner Izabela Roza Lechowicz who also died in the crash, while a tearful Aiywatt and the squad saluted the fans from the pitch after the game.
Both the hard period in Leicester's recent history and their love for their fallen owner are on full display in a six-minute video shared on the club's Twitter account on Saturday.
"He donated money to charities, to hospitals, and that hit me hard as well, because my son's been poorly".
About 10,000 supporters had earlier walked from the city centre to the ground, led by injured player Harry Maguire, waving Leicester FC banners and Thai flags along the route in memory of Vichai Srivaddhanaprabha, who was also the club's owner.
Thai billionaire Vichai Srivaddhanaprabha was killed when his helicopter crashed October 27 in a parking lot next to the English Premier League club's stadium.
Puel praised his players for the way they handled their emotions at Cardiff last weekend, where Demarai Gray's goal gave Leicester a 1-0 victory in what was their first match after the crash.
A tribute video will be shown on big screens before the match and a two-minute silence will be held to honour the armed services as well as the five victims of last month's accident.
The second-half shirts will bear the embroidered poppy symbol in honour of those who have given their lives in war, with the match selected as the club's annual remembrance fixture, 100 years after the end of World War I. "I am hoping everyone in the Fulham family shares my heartfelt sentiments for Slavisa and joins me in wishing him success and good fortune, wherever his next stop may be".
Tributes left at the stadium are to be moved to a memorial area. Fans will receive commemorative scarves and souvenir matchday programmes in honour of the club's late chairman.
"It is not easy to prepare for this game".
