Blogs are using template software and unless your blog is about blogging (as oh so many are - how many people blog just about wordpress? hundreds if not thousands), the key words that are tripping contextual ads on blogging-related subject are mostly in the template.

So you don't need to cloak or anything, just use Adsense section targetting to make the contextual engine either ignore the template part or to select just the content part. You would probably want to use the former strategy so that your navigation links would help determine context, but I suppose that depends. In any case, you could get rid of the blog roll part, the "powered by Wordpress" or whatever credits there are and stuff like that.

As Google details on their section targetting page [google.com]

The HTML tags to emphasize a page section take the following format: <!-- google_ad_section_start --> <!-- google_ad_section_end --> You can also designate sections you'd like to have ignored by adding a (weight=ignore) to the starting tag: <!-- google_ad_section_start(weight=ignore) -->
