Here's a pic of my set-up. It's a 20 long that houses 4 fbt.

Its split down the middle by a plexi wall I glued in place with aquarium sealer. The land is a layer of gravel covered with plastic mesh topped off by coconut fiber. The plants are live. The water is about 4" deep and filtered by a Tetra Whisper 10i filter. I use a low-watt basking lamp when needed to keep tank temp between 70 and 78. I use a standard florescent grow light for the live plants (the toads don't really need it, though it won't hurt). I mist when necessary to keep the plants healthy. The tank humidity stays between 70 and 85 percent.
Any other questions I can answer, just ask.
