When I'm developing new races, I try to identify some distinguishing trait and build upon it.
For example, I created a race of creatures that were a kind of "rodent-man". They were furry, with long teeth that continued to grow throughout their lifetime. The two traits I concentrated on were the color of their fur, and those ever-growing teeth.
Their society turned out to be stratified by the color of their fur. "Common" or lower-caste members tended to have gray-ish fur, which is actually comprised of all colors of fur mixed together more or less uniformly. The upper-caste had fur of a single solid color (white, roan, black, whatever), or very few colors, but with distinguished regions - so "spots" were ok. The point is that the lower caste has "mutt" fur, while the upper caste had more "pure bred" fur.
As for the teeth ... well, rodents need to continuously chew to wear down their teeth, so these creatures were constantly looking for things to chew out of necessity. A significant sector of their economy was based on supplying "quality chewables" for the wealthy. Only poor folk wood chew on common wood, or old wagon wheels. The rich would import only the finest items, rare woods of delictable densities and exotic flavors!
So, by taking just a few rather mundane elements from the race and building on them, the race gained a whole lot of flavor.
I'm not sure what do to with dwarves off the top of my head. Maybe you could do something with their diet ... I mean, what *is* there to eat underground anyway? I seem to recall something somewhere about dwarves eating rocks; that could be an interesting twist.
