I have studied the following thread which gave me a lot of answers to my question.
Split Gas Line to Gas Water Heater for Gas Dryer
I still have some follow-up questions and would appreciate if someone could help me with these. I currently have a water heater connected to a gas valve in the wall. I need to split this line to connect to a gas dryer as well.
I am thinking of doing the following using standard connectors. Is there a better way of doing this? Also, is it OK to use Teflon sealing tape to seal the connections.

You need to check with local code enforcement. I suspect they will want you to explain how you know your gas line will supply enough gas flow (in BTU/h) to supply both appliances simultaneously.
Then I think the code will require you to use black iron gas pipe in separate lines to individual cut off valves for each appliance. Probably you could leave the existing valve in place, use an adaptor, and place a black iron Tee there leading to two individual valves. Then at those point connect the light, flexible corrugated supply lines.
I don't think code enforcement will allow the light corrugated supply lines to have a Tee in them.
There is a special type of (yellow colored and thicker) Teflon tape for gas connections. Also there is pipe dope designed for gas connections.
