You're doing the same thing as getting there but in reverse. When you're in Duna orbit and want to get back to kerbin, you have to remember that you're technically in a higher position around the sun than Kerbin is. As such, you're going slower and and will need to both descend closer to the sun and speed up to meet Kerbin as it passes under Duna's orbit. To do this, just wait until Kerbin is behind Duna by about 15/20 degrees or so and set up a maneuver and see how close you are to meeting Kerbin on the other side of the sun. Presumably it should be close enough and you should be able to adjust time and/or the maneuver to get close enough for an encounter. 

Forgot to say. When you want to raise your sol orbit, you'll need to accelerate with your maneuver node on the other side of the planet you're orbiting from the sol (Camera sees sol behind planet). When you want to lower it, you'll need to put the maneuver node on the side of the planet facing the sun. (Sol should be behind the camera as you're initially placing the node.)  

Hope this helps

Try going from Minmus to the Mun for practice. It's very similar, but the flight times are much shorter and the stakes much lower.
