Welcome to the forums, Milky.
With that size of a fish tank, you're best bet will be some of the smaller, more managable plants like Drosera, Pinguicula, and the smaller Utricularia. You should go over the
carnivorous plant FAQ by Barry Rice for a description of these plants and their needs.
However, a few things stand out, as far as your setup goes.
First, incandescant lights just won't cut it. They produce way too much heat and not nearly enough light. If the hood is the right size, replace the bulbs with some compact fluorescents (you can get compact fluorescents specifically for plants at home improvement stores and such, but grow-bulbs aren't strictly necessary. If the hood can't accomodate compact fluorescents, you'll either need to replace it with a fluorescent hood or get some gooseneck desk lamps and stick some compact fluorescents in them. I suppose you could also get a small fluorescent strip light, but with a 10 gallon tank, it might not be cost effective.
Second - wash that gravel! Carnivorous plants eat bugs because they occur naturally in substrate with almost no nutrients. The roots of most CPs are very sensitive and will burn when exposed to any fertilizer for very long. If you have some conventional houseplants around, give them the fish emulsion - they'll be very thankful for it. CPs, unfortunately, will not.
That gravel in the bottom of the tank may not be entirely necessary, either. A planted terrarium is hard to set up; all the plants must like the same type of watering, light, soil, and climate conditions. It's also hard to maintain; some plants are more aggressive than others and will quickly overgrow the container, and if a disease or pest gets loose, the whole terrarium must be treated. A less maintenance-intensive route is to grow your plants in pots inside the terrarium. The simplest way to do this is just use the terrarium as a giant drip tray, with the pots resting on the bottom (or propped above the water table if necessary.) A more attractive variant on this method is to bury the pots in a managable substrate (like aquarium gravel) or disguise the pots with rocks, pottery, pieces of wood, plants (Spanish moss and Sphagnum moss are good choices,) etc. This way, each plant can have the soil and water it likes best, and you only have to worry about choosing plants that like the same temperature and light.
As far as plants go, the sundews (Drosera,) butterworts (Pinguicula,) and bladderworts (Utricularia) all have very charming flowers that come up seasonally (two times a year on many varieties.) An Asian Pitcher Plant (Nepenthes) makes a nice addition; it doesn't have very impressive flowers, but the traps (pitchers) are about as much fun to look at as any flower. The Sun Pitcher (Heliamphora) is another good terrarium plant, but I'm under the impression that they aren't the easiest carnivore to grow. Whatever plants you choose, research them first to make sure you get varieties that will succeed in your home - be especially sure not to make the tragic mistake of buying an outdoor plant such as a Venus Flytrap (Dionaea) or Trumpet Pitcher (Sarracenia) and having it waste away in the winter, when they demand cold to frosty temperatures.
You might want to have a few non-CPs too (watch the evil eyes on me from the CP purists.) Tillandsias, the air plants - including Spanish moss - make good companions to CPs, as they thrive on humid air rather than soil and water. Many orchids would also do nicely, provided with good air circulation. I'm sure there are many others, but that's what comes to mind immediately.
Here are some simple CPs for the terrarium:
Drosera adelae
Drosera aliciae
Drosera capensis
Drosera spatulata
Drosera hamiltonii
Drosera schizandra
Pygmy sundews (Drosera, too many to list)
Utricularia sandersonii
Utricularia livida
Utricularia longifolia
Nepenthes gracilis
Nepenthes ampullaria
Other lowland Nepenthes species and hybrids
Pinguicula moranensis
Pinguicula esseriana (very attractive, if you ask me)
I hope that helps!
