The businessmen died along with four others when his helicopter crashed outside the club's stadium last Saturday.
After the emotional return of the Leicester City squad to footballing duties on Saturday, in which they won 1-0 away to Cardiff, Schmeichel detailed the events of the tragedy that will live with him for the rest of his life. It was something that will stay with me, unfortunately. "We will be ready but I hope we can find a good balance between conviction and emotion in this game because if we remain just on the emotion it will be hard". It's not a nice memory but I've had all the support that I need.
Numerous players were scene wearing club scarves as they celebrated the win while supporters had banners and messages of their own in tribute to the owner.
Fans wore T-shirts with Vichai's picture on it, underneath the words "The Boss".
Later, Schmeichel, who has made 303 appearances for Leicester since being signed by Srivaddhanaprabha in 2011, penned an emotional tribute on Twitter.
The Premier League match in Cardiff will be the team's first since the incident after the midweek League Cup game against Southampton was postponed.
"We have had some great times", Schmeichel said of his team's exploits under Vichai's eight-year ownership.More news: Trump says Democrats would ruin Florida, his second home
Schmeichel said he was shaking in his boots during their warm-up before the game and was in tears during the minute's silence before kick-off, BBC reported. "We did it for him and his family". We talked about having to just stick together and be what we have always been - a family.
"When he took over this club it was in a pretty precarious situation, and to build what he has is quite awesome".
"It's one thing building a team and a club, but we are all more proud of being part of the family that he created".
The Leicester players and staff also paid tribute to their former owner with the club's travelling fans after the final whistle.
"It's been a odd week, surreal really, and I'm glad it's out of the way if I'm honest", manager Neil Warnock said.
Others who died when the helicopter came down in a vehicle park were two of his staff members, Nusara Suknamai and Kaveporn Punpare, pilot Eric Swaffer and his partner Izabela Roza Lechowicz.
