I think it is more the social than the academic skills that are important to teach your daughter before she starts kindergarten next year. She needs to be able to follow directions, listen and do as she's told, sit still when it's time, etc. If she can do all of those things, she'll do fine in kindergarten.
She'll also benefit from working on her fine motor skills, like cutting with scissors, holding a pen/marker the right way, etc. Those are easy to work on at home - just do lots of crafts and art projects. Mazes and coloring books are great for working on fine motor, since it encourages her to follow a path or color/draw within the lines.
For the academic side, get some workbooks that you can do at home, read to her often, and make learning fun and playful. You can teach her everything she needs to know at home. Just make sure she's up to speed on being able to listen and follow directions.
