It would make sense to start with sun salutes. Backbends, twists, and inversions are also good for revving up energy. Just remember that your body will be stiffer in the morning, so take it easy on your muscles and make sure you get them really warm before trying any advanced postures.

Surya Namaskar.
Sun salutations are a very easy energizing morning practice.
A good place to start. You could take a few breaths, do four sun salutations, and finish with a few breaths.
This is about a five min. practice. You could add more later.

I would add Handstand (against the wall, of course) to the above recommendations. If you want to energize, you need to invert & I think handstand is the best for this.

Nadi-Vayu-Yantra (rtsa-rlung 'phrul 'khor) sequences are often very dynamic and very energizing. In addition, practicing outdoors is invigorating especially if it is a little chilly.

Yeah, Inversions right when you wake up are like a cold shower while you're still in bed. At'll do the trick alright!

I'm just not an AM Yogini yet but what sounds best for me, as I sit in my chair and wonder what an early morning practice might feel like, are seated forward folds, followed by some seated side folds w/ arm lifts (like Upavishta Konasana but with one foot into groin) gradually working my way from the ground up to some more heat generating Postures. (Adho Mukha Svasana, Plank, Chatturanga, Urdva Mukha, throw in some leg lifts in Adho Mukha, maybe a nice knee bend leg lift for the hippies. . )

I CANNOT practice Pranayama in the morning without falling right back to sleep, even if I'm seated upright. I know! Pathetic, right?! I have to do something physical first, followed by Pranayama.

Thank you to ALL!!! I have been practicing yoga for about six years,
and i am an aweful morning person! don't know, could be a Pitta thing, but
I really detest mornings, and i wanted to see what others think and do on the subject.
I have been doing some sun salutations in the am for the past two weeks, it's a nice
start, i do think i will be trying some inversions to pump myself into gear. I thank you all
for your input!

namaste~

Since people mentioned being really sluggish when you first wake up - here's an idea to ease yourself out of bed - before getting out of bed, roll onto your left side and lie there for a few minutes - this opens the right nostril, stimulating the pingala nadi, which is energizing and warming and helps wake you up.
Then brush your whole body with a dry body brush.
Then if you're courageous take a cold shower, it's really great for the immune system too!
