Well, what exactly are you looking for?

There are no sources showing an increase in excess death due to vaccination because the medical and media establishment categorically deny that this could possibly be happening. As far as they're concerned more or less nobody ever dies of the COVID vaccine, period, end of story and any claim to the contrary is misinformation. This attitude is sometimes summed up as "Vaccines are amongst the leading causes of coincidences".

The US VAERS database of course tracks peculiar diseases/symptoms/deaths that follow vaccination. At this point it has more records of adverse events for COVID vaccines than all other vaccines combined since the tracking programme began, but the vast majority of problems never make it to VAERS or similar databases, so the absolute numbers aren't that useful. So the best people can do is inference. There appears to be a sharp increase in deaths due to heart attacks and strokes/other clotting disorders this year. The media are occasionally reporting on this but either claiming it's some inexplicable mystery or coming up with some absurd alternative explanation. Examples:

"Health experts have been left baffled by a big rise [25%] in a common and potentially fatal type of heart attack in the west of Scotland": https://www.thetimes.co.uk/article/mystery-rise-in-heart-att...

"Why are heart attacks becoming common amongst seemingly fit people?" - their answer is a sudden epidemic of too much exercise: https://timesofindia.indiatimes.com/life-style/health-fitnes...

The UK has very good public health data compared to most countries. It breaks out heart related deaths for both with and without COVID. There has been a large rise in non-COVID heart deaths in 2021. Some of this may be/must be due to the (not really admitted) collapse of the UK healthcare system due to lockdown triggered overload. However there is also a correlation with the vaccine rollout (it's graphed):

It's a 12x increase. That's either lockdowns or vaccines but whichever it is, that's not a natural cause, it's caused by government policy.

From a quick bit of Googling there seems to be similar data from Israel but I have not checked this tweet in any depth - the tables seem legit but the summarization of it looks backwards to me:

Anecdotally there seem to be a noticeably larger number of athletes having heart attacks whilst playing. Example montages of these stories are here: https://www.youtube.com/watch?v=1l34v01crsc https://www.youtube.com/watch?v=JZAPxYouf-c

I have a friend who is investigating this phenomenon in more depth. He found a research paper from the early 2000s that counted news reports about sudden on-field medical emergencies amongst young sports players, then compared that rate to some big lists of news stories in 2021 about it he compiled. He's still working on this project and hasn't written anything up publicly but so far it seems the rate is 6x higher than normal. Obviously this sort of investigation is limited by several factors, but as public health agencies refuse to investigate or report on this stuff, there's a limit to how far random members of the public can go.
