Great topic. Here are a few off the top of my head.
I use bats that accept 6" bisque tiles paired with brackets on my wheel that accommodate a large ware board (it's a Bailey wheel). Got the bats from a company called Euclids out of Canada and the tiles you can order inexpensively from pretty much any place that sells bisque. This bat system allows me to throw a dozen small pieces without getting up or having someone move my board as often.
I have 5 gallon buckets next to my wheel full of the balls that I need to throw for the day. I also try to keep all of my tools in one easy to reach place.
I use a pointer to guide me (made from a skewer and a lump of clay stuck to the side of my wheel) so I only have to measure the first pot to get accurate measurements.
I use a rolling cart to move ware to/from kilns. Less steps = more efficiency.
