Ramsey - currently recovering from injury - sat in the stands for Cardiff City's 5-0 thrashing of Plymouth Argyle last weekend and shared his tactical analysis with interim manager Omer Riza on the touchline.
"I've been around the [under] 18s a few times at Cardiff and been lucky enough to coach them," said Ramsey.
"It's addictive as well and you do watch games differently."
Ramsey has not played since suffering a hamstring injury in Wales' away win against Montenegro at the start of September.
He has resumed training but missed this month's return against Montenegro and trip to Iceland, and it remains to be seen whether or not he will be fit for Wales' final two Nations League fixtures against Turkey and Iceland next month.
Wales are unbeaten in four games under Bellamy and Ramsey has been impressed with the recently appointed head coach.
"He's come in and him and his staff have been a breath of fresh air," he said.
"They are so detailed with the amount of information they pass on, and I've been really impressed with them.
"With the talent we have in this Welsh team with Brennan Johnson, Harry Wilson and other players as well, we can hurt teams if we get the structure right behind them."
