For scientific/technical talks specifically, a truly useful technique I learned from The Craft of Scientific Presentations[1] is the assertion-evidence slide.

This type of slide has a complete sentence at the top that makes a substantive assertion. Then the rest of the slide contains evidence for that assertion usually in the form of a diagram, chart or table. This type of slide is the backbone of a scientific presentation.

Generally, Alley's book is extremely useful.
