Have you tried taking control of his perception of your working day? I've had bosses in the past where the only way to manage them and their expectations was to maintain a narrative of what you were up to.
Perhaps you could schedule a weekly (daily) catch-up with your boss to explain what you're doing, any issues you've had etc. If he won't commit the time to sit down with you, email him a bulleted list of what you're doing that week/day. Don't get lost in the detail but try to highlight any particular wins (e.g. "the database server we'll need for the quotation site is up and running") and any particular roadblocks ("[web services firm] haven't sent the documentation through I requested. I've scheduled a call for Monday to try and get it sent"). If you're not making the progress you expected/hoped for, always present it in a positive light by explaining what you're doing to deal with it.
If he is always coming to you to find out what you're doing, it might be that he's doing it at the wrong time for him (when he's dealt with all his crises and is tired/stressed) or for you (when you're having a short HN-break in which case you appear to be 'always' slacking).
