Walk in the tall grass to encounter Entei. You can also use the Repel item to prevent other Pokémon from appearing as you search the grasses for Entei.
You can also use Mean Look to prevent Entei from running. [4] X Research source
You can use Snorlax’s Crunch to weaken Entei. Then hold Leftovers to regain XP as Entei attacks. [5] X Research source
If Entei runs away, that’s ok, go heal your Pokémon at the nearest Poké Center and return to where you last encountered Entei. You’ll have to search for him again, but his health will be the same as when he ran away last time.

You’ll most likely need to go to an area where the city limits meet a route (any city, including Ecruteak City, Violet City, and GoldenRod City) and continuously run in and out of the city and check your map. Every time you run out of the city’s limits, you’ll see on your map that Raikou is in a different area. Repeat this process of running in and out of the city’s limits until you see Raikou close to you on the map and you can run over to his location.

Suicune isn’t like Raikou or Entei since it can’t be caught randomly. You have to go to certain locations to encounter Suicune before you can capture it. You also don’t need to prevent Suicune from running from battle, so you won’t need your Snorlax or Gengar.
Use False Swipe to keep Suicune at 1 HP, so you don’t accidentally defeat it. If you defeat Suicune, that’s ok, go heal your Pokémon at the nearest Poké Center and return to the burned tower.
