Here is one, and White to play mates in one with a pawn.
8 
7 
a Everything a mate needs is there and none of it is unusual. The pawn goes to g7 and attacks h8 the way any pawn attacks the two squares diagonally in front of it. The black king cannot capture on g7 because the f6 pawn is watching it. It cannot go to g8, because the bishop on a2 sees all the way down to g8 on the long light diagonal. And h7 is occupied by one of Black’s own pawns.
Pawn checks cannot be blocked
This is the part worth remembering even if you never mate with a pawn. Every other checking piece except the knight can be blocked: you slot something in between and the check is over. A pawn giving check is standing diagonally adjacent to the king, so there is no square in between. Your only two answers are to take the pawn or to move the king, which is exactly two of the three ways out of check.
That is why a supported pawn check is so much stronger than it looks, and why pawn checks come up in mating nets far more often than pawn mates do.
Why you rarely see one
A pawn attacks two squares. To mate with it you need the enemy king boxed in already, a defender for the pawn, and cover on whatever squares are left. Most of the work has been done by other pieces, and the pawn just puts the lid on.
In real games the pawn usually mates by turning into something else first. A pawn reaching the eighth rank promotes, and a new queen appearing on b8 with check ends more games than every pawn mate in history put together. Every so often the promotion is to a knight rather than a queen, because a knight landing on f7 checks a king on h8 and a queen landing on f7 does not.
If you want to train the moment of recognition, mate-in-one puzzles throw up a pawn mate every so often, and they are the ones people miss, because the eye goes to the queen first.
