Just a conjecture: I have noticed that some sites nearly vanished from the Google search results after a layout relaunch, even if the actual content is still there and the URLs did not change. After some time the sites were visible again - this could be weeks or even some months. This phenomenon appears to be triggered by changes of the entire site or large parts of it. Maybe there is some kind of global re-evaluation of the site going on at Google... but only some Google engineer could tell us about the details. I would expect that your blog will soon be visible again. Maybe it helps to be a little bit more active than usual, like writing more articles, getting some attention from the web, and finding some alternative ways to get visitors to your site. But as I wrote, this is just a conjecture. Solid explanations regarding search engines and their secret ranking algorithms are nearly impossible most of the time - too many variables are involved and the web is just so very big...
