Maybe you're missing edges in your borders. You'll need to use more edges in your borders to fix the shading.
When you are working with low poly objects and don't want to use hard edges, add an extra edge to your borders to make it look like a rounded bevel, with soft edges and a high geometry approximation angle. Doing this usually give you smooth polygons when subdividing too. You can try with split edges with split control. This is a graphic from my blog when I was experimenting with bevel and extrude to achive this effect. The result wasn't perfect but it did the job done back then when I was modeling some weapons for a game title.
