I have a "log file" for each week, broken down by day where I keep track of my TODOs and check them off. I put little notes next to the todos that describe what exactly I did, but not in much detail. But I can easily go back to 12/05/2011 and see exactly what I did that day. I usually plan one week in advance, but I only put task details there once I actually figure them out.
"What did I do last time I worked on that project or for that client?" is more difficult. I'm a fan of using blossom.io + Slack (slack.com) for large projects or startups. Usually there is only one such project I am working on. If you have lots of different project then these tools may cause too much overhead...
