For structure and content, start by copying stories you like. Take well-respected short stories, even fairytales, and think what make the stories interesting to you. Then work with these elements to build your own short stories.

For verbal delivery, go find some highly-rated audiobooks for kids, and pay attention to how are the narrators using their voice to tell the story. Then, same as with what I said above, take elements that you think work and that you like, and incorporate them into your own style.

Finally, you need to practice a lot, and try new things as you discover them. Once in a take, sit down and take notes on paper or in a file of what has worked and you should keep doing, and what hasn't worked and you want to improve or stop. Rinse and repeat.
