Basically carry on doing what you are doing. The more organic material you can add the better.
Some people may say add sharp sand or grit, but to be perfectly honest in our previous 'grow taller' clay soiled garden (as you walked across it, you got taller 'cos the clay stuck to your boots), we found it made little difference.
Do try to avoid walking on the soil when it is wet though. It compacts it and makes it harder to work on.
