Nearly all supermarkets that I've been in in recent years sells a version of "creme cake" - butter, vanilla, blueberry, chocolate, lemon and more - either as a loaf cake or bundt cake. While I've only tried a few of them, what they remind me most is the lemon pudding pound cake that my aunt used to make - you know the one that has you poke holes in the cake that help absorb the lemon glaze deep into the cake. Moist, sweet and flavorful, heavily glazed, a bit dense but not as dense as a pound cake. Is that a description of the kind of cake you are looking for?
I did some research for you and haven't been able to come up with a clone for supermarket creme cakes. I can tell you that in the supermarkets, they're made from specialty mixes and thet they contain oil that makes them as moist as they are.
You might look for recipes like this and add a glaze - it's made with a box mix, sour cream and oil - as a starting point

If you don't want to use a cake mix, what you might do is make an inital one using a mix anyway and see how close it comes, then work on replacing the mix with a from-scratch recipe.
Have fun!
