If possible at all try to tell a story in order to get your audience involved. Admittedly, this can be hard especially with technical topics but even a somewhat lacklustre, unimaginative story ("Imagine you were to build a CRUD app ...") is better than merely walking the audience through a technical manual. Use pictures and simple diagrams to underline your message. Another personal principle of mine for creating presentations is this: - Bullet points - are - the - devil's work. I really don't know why bullet points are the default template in most presentation software. They lend themselves to being misunderstood as notes for the speaker to simply read off. Even for actual lists in presentations bullet points mostly fail to get the message across. Besides, they make your presentation look cluttered. The most important aspect of preparing a presentation though is practice. Usually I practise a presentation until I almost know its contents by heart. This allows me to improvise and makes me feel comfortable during the talk.
