If it truly is malt extract powder, you can make beer. Bread yeast isn't a great option, but it will work and many people have had good success with it. Its biggest problem is consistency from batch to batch.
The most important other ingredient you'll need are hops. If you don't have access to a brew store, try a well-stocked garden supply store. Some sell hop plants. If you can't find hops, you'll need to locate another bittering herb (wormwood, heather, mugwort, etc). Do research on the beverage "gruit" which is unhopped beer to get more details.
I would start with 3.5 kg of powder and boil that in 10 L of water for an hour. As soon as the mixture begins to boil, add your first small amount of herbs (no idea how much to add as I don't know your herb selection, but we can probably help more after you select your herbs). add another small amount after 40 minutes. If you have used an herb that smells pretty good, add one more small amount 5 minutes before the boil is complete.
From then, add another 10L pre boiled (then chilled) water to a carboy or bucket. Ensure the mixture is less than 75 degrees fareheit (only conversion I can't do in my head) and throw in your yeast. Store it in a cool dark place and wait for 4 weeks (with some way for co2 to escape). There's your beer!
Can't say how good it will be because there are too many variables, but it will be beer.
One huge thing to keep in mind is that cleanliness and sanitation are essential. Anything that comes in contact with the liquid after the boil must be sanitized including the fermentation bucket. Since you say you don't have a brew store, you probably have no way to purchase a no-rinse sanitizer. You'll need it, so try this. Make a no-rinse sanitizer by mixing 15mL bleach, 15mL white vinegar, and a pinch of salt in 20L of water. Make it in your fermentor, let it sit for half an hour and soak any utensils you will use. Then dump it out and pour in your wort (unfermented beer) and yeast.
