It's hard to say what you can do to stay relevant, because I don't know what industry you are in and what your qualifications and experience is.
Experience is what can set you apart from the rest. Emphasise that. If there are still opportunities in your industry then work on learning more in it. If you keep learning in combination with the experience you already have + the experience you gain with the things you are learning, will make you an expert in the field.
Try to find ways to be more useful in your job.
The more useful you are the more invaluable you become to your employer.
All the best to you and your buddies.
