Practicing with many forms of Divination until you find the right one for yourself as
@Mider2009 says.
Try really Meditating and Working with the Tarot, Runes, Geomancy or something else etc.
Try different Scrying Methods as well... Black Bowl, Black Crystal Ball, Black Mirror, Black Screen, Obsidian Disk or something else etc.
Also spend time with Visualization exercises that utilize Your 5 Senses. Really Visualize being able to Taste, Touch, Smell, See, and Hear on the Astral and Etheric Planes.
Pathworking is also a great way to put these things to use and develop them.
Having said all that it's also worth mentioning that not everyone will be proficient in every type of Magickal Talent.
It's a Great thing to Practice and get better but also you don't want to beat yourself up over it or feel bad if it's not you specialty or even a Strength.
I liken it to Playing a Musical instrument in a way. I can practice and play songs on the Guitar and be 'Good enough' that it works and I can make Music. But also I don't have Perfect Pitch where I can hear what the Exact musical notes are that I'm playing and I'm also not talented enough to be someone like Jimi Hendrix.
That's Okay though.... I'm still making Music anyway.
For what it's worth Clairvoyance and Clairaudience are not my specialty either. I practice so I can be better at it but I don't beat myself up over it either.
I use the Tarot and Obsidian Disk Scrying myself to work on these areas.
I hope that some of this is useful.
