I don't know about the hormonal thing, but it's definitely an age thing. They're branching out, at the cusp of greater independence, but frustrated at their continued reliance on the big people around them. They're not quite ready to actually get out and run for themselves, but gee they want to.

If you're going for consequences, then like peanut says, I'd try and go for the here and now. Tomorrow, even later today, is too far away for them to even care.
If my kids use something inappropriately, then they lose it, for eg. But they can have it back another day when everyone's calmed down.
At bedtime, we remind the kids that they've only a certain amount of time and they need to hurry up or they'll miss out on books. It rarely actually happens. I think it's easier for them to get it, too, if there's an obvious link between their action and the consequence.
And, personally, if they do something wrong and then again and again, I'd let it go, rather than piling punishments up on top of one another. I think adding can discourage them from trying again.

When my kids are like this they're angry and annoyed and it doesn't matter what I threaten them with, they just have to get it out. It works better to just be there, staying calm (ha! ok, that doesn't always happen) so they know they can calm down, too, and then we'll talk. We often feel like we have to jump in and punish any infringement, instead of maybe looking for ways to talk it out and help them learn ways of dealing with things differently the next time. It's a slow process, but I see my kids starting to figure this out for themselves with time...

Anyway, your happy little boy is still there, he's just having a hard time right now. How much fun time do you get together, just you and him and having a good time? That always helps.
